A common challenge faced by all of mankind. And ask them how theyre doing in paris with the. 2 good. Going it alone is not a good decision for anyone and hes not possible for everyone and its the root of future conflict. We hope that the us can take on more responsibility and make more constructive contributions to the process of multilateral cooperation instead of adding negativity. Also coming up this week 30 years ago the berlin wall began crumbling exposing east germanys vast web of lies betrayal and this option made possible by the secret police. At 7 am on april 30th 980 observations of residents must undertake this month has someone looked into my life and i had no idea about it. This is made me feel very uncomfortable. To our viewers on p. B. S. In the United States and all around the world welcome we begin the day with a dire warning from scientists about Climate Change a warning based on evidence versus a Campaign Promise from u. S. President trump a promise based on a calculation of how best to keep the president s base this week the Trump Administration gave notice to the United Nations that the u. S. Is exiting the paris climate agreement the worlds richest economy and biggest polluter has become the only nation to read neg on the only International Plan designed to stop Global Warming the Paris Agreement is not binding it does not require a country to spend taxpayer money and yet that is how the us president has always described the United States will withdraw from the paris Climate Court but begin negotiations to re enter either the paris accord or in really entirely new transaction when terms that are fair to the United States its businesses its workers its people its taxpayers so it getting out. Of americas exit will become final in the venture of next year one day after the us president ial election timing is very relevant here this weekends the us started its withdrawal of love in the 1000 scientists declared a Climate Emergency predicting untold suffering unless we change our pursuit of limitless wealth and growth with no wind the world always watches the u. S. President ial election closely because of its Global Impact but the events of this week give even more weight to election day next november. Well a republican strategist and former advisor to u. S. President donald trump has gone on trial in washington accused of obstructing Justice Roger stone was investigated as part of the special counsel probe into russian meddling in the 2016 american elections in case the insides with the impeachment inquiry against President Trump is taking place in the u. S. House of representatives. Like few other political operatives in u. S. History roger stone revels in attention whether its good or bad. Oh. God. No im. A veteran republican strategist whose career goes back more than 40 years roger stone counts former u. S. President S Ronald Reagan and Richard Nixon among his clients his affinity for nixon apparently Strong Enough for him to get this permanent reminder his ties with donald trump also go back decades in the eightys stone turned trump the entrepreneur into a major donor for reagans campaign and saw in him a potential contender for the white house. I have great affection for trump and the trump family i have wanted him to run for president society 88 but while dirty tricks and prince of darkness are among the kind of names his critics used to describe him style now faces a new one convicted felon indicted by special counsel Robert Muller who was investigating russian interference in the 2016 campaign stone was charged on several counts. The central question. Tipped off the Trump Campaign that the wiki leaks website was about to publish hacked emails supplied by russian spies as part of the coordinated campaign to sync trumps democratic rival Hillary Clinton i will not kill these charges and i will defeat them was i believe this is a politically motivated investigation the ruling class is found guilty of political provocative could now face jail in the style they say hi low profile trial is set to test run just times long held theory that any publicist is good publicity. This week germany is celebrating 30 years since the fall of the berlin wall on nov 9th 1909 east germanys communist regime lifted travel restrictions on its citizens allowing them to cross into the west for some it meant finally being able to escape the long arm of these germanys secret police the stasi and the stasi consisted of visual and not so official associates who spied on hundreds of thousands of citizens many had no idea that the stanzi had collected information about the mental years later when their secret police files were made public that brings us to the story of 2 women that the stasi was able what the stasi was able to do to their lives as had all kinds of impacts then and even today. Under lunas aber visit the building where they used to live. When the 2 secretaries lived here in their younger years spies from the stars he used germanys secret Police Monitor them through the kitchen window. But then the tree was smaller i was even dizzy do you see people from the stars he standing there no as for me i just recently read about it. We never would have thought of such a thing. No i dont think so either. They read about it in the stars the files a couple of 100 pages of intercepted letters private mail and official correspondence and most of all reports from spies including the layout of your loan as aber and zilker all files flat. At 7 am on april 30th 981 observation of residence was undertaken for this kitchen light was on and the window was half open about 50 minutes later when the light was turned off and say bang left the plant alone she walked in the direction of the summer he touched us a subway station at zoom on had someone looked into my life and i had no idea about it this is made me feel very uncomfortable for years i didnt want to have anything to do with it i didnt even want to read the file on the news. Its there. But i have to live with it. In my experience you always get through life better if you can live with a situation with. That. They wanted to leave east germany they had applied for exit visas it was here that they were subjected to hours of interrogation they never wanted to set foot in this place again. Lets just go and you have to go back to the place of horror. But i have a really bad bodily feeling really bad i could just cry then do it. Now. To this day they feel humiliated by the tone used in the interrogation. This is here. This is this you know. So is a greeting it was like can see right away that your slant can be not only that of you better watch out dont even cross the street the wrong way we are everywhere are just huge threats nothing. That was more than 30 years ago only universe 3 of the full of the berlin wall the stasi Documentation Authority made the files accessible still killfile him alone is able to speak publicly about what happened there explaining to young germans why they risked their lives to leave east germany. Dubose i wanted out and i didnt want anyone to tell me who has the right to decide where i live even if it were social or whatever but we didnt want that and at that age youre also brave enough to do it and it is most does he even somehow never getting out or only to a couple of countries that it was decided i could go to i never agreed to that i had said before that i wasnt happy with that and then i thought you know i just want out of here i want freedom which meant if i had but at some stage it will petered out both women withdrew their exit visa applications. To pasta and thats allowed her to travel alone as a ba had a baby and was allowed to go to the west after all. Was well after the berlin wall fell in 1809. 00 negotiations known as the 2 plus 4 treaty talks resulted in the reunification of germany in just under a year of that historic change was part of an agreement between the 2 germanys east and west was the 4 former Occupying Powers following world war 2 the soviet union the us france and. Robert zoellick led the u. S. Team in those to pause for negotiations we spoke with him earlier today here in berlin. Robert zoellick in 1989 most people said that the full of the book in will came as a complete surprise to see its not the exact opening of the wall which i think was an accidental occurrences historians have have now uncovered but in from the start of 89. 00 when i was with secretary baker over at the state department the ground was shifting in part because of the changes that gorbachev and least in part because of the failures of the east german regime in part because of the courage of people in east germany in the demonstrations so you knew that you had to be able to respond to the changes and there were some steps that we started taking earlier in 89. 00 with conventional forces and changes in nato to do that to be prepared to work with germany as a partner whatever came in that was fortunate you took part in the process of bringing that to germanys together what was the United States main role in that well i think historians will agree the us was the strongest supporter of west germany in this and we were fortunate our publics were not anxious about german democracy in fact you know they there was a sense among the American Public that of course germans would want to unite and that allowed us to play a role with nato with the changes in dealing with the soviet union with the sort of c. F. C. Process what i described is in a sense a moving circus of sort of different aspects that had to be changed on the International Side to allow germany to unite from the perspective of today was german unification handled well was it too much take over and not enough. I really dont think there was an option and you know one also has to keep in mind germany had 40 years west germany had 4 years of International Commitments if youd started to create a new germany all of a sudden you would have had to redo all those so if you like bricks in. You would have liked that so i think there really wasnt an option of that and frankly i think one chance or coal over the lot of foresight sort of used the elections in i believe march of 90 to sort of have the choice of these german people that was the key decider now what follow from that in some ways understandably the people of the Eastern States you know had been under 40 years of communist control a lot of younger people entrepreneurial people moved to the west beforehand the industries were not really that productive so it was going to take at least a generation or transition but i frankly am always pleased when i meet people from east germany who have lived a totally different life now because of that experience theyre often the younger ones so one has to help people perhaps my generation that had a harder time making the change but its great to see the freedom that people now have and any lessons from german unification for all the world of today and tomorrow well theres a lot of lessons i mean one was at the same time we were trying to keep a 40 year promise to the german people we really also wanted to build a partnership for the future and we believe that the united germany would be the most influential country in what we knew would be an integrated europe and we wanted to have germany is a good partner so i look with some concern at what i consider to be the drift away or even alienation between the 2 countries theres another big picture though that could be useful for the irans of north koreas which is that when people try to just deal with the Nuclear Weapons and sanctions alone i think they missed the fact that a case like german unification required changes in the conventional forces that change the required and economic dimension it required a human rights to mention that required. Changes in sort of the short range Nuclear Forces the changes in c. S. C. E. So you had this multiple ring circus and i think frankly to deal with countries like iran and north korea youre going to need a. Multidimensional approach Robert Zoellick thank you so much pleasure. In that was robert there speaking with g. W. So im young earlier today all this week w. Will be bringing you special coverage and reports on the events which led to the fall of the berlin wall 30 years ago. On one extrusion ism and social media spying both part of what is known as digital of or tyrian ism and theyre threatening democracy around the world thats the message from this years report on global web freedom published by the u. S. Watchdog Freedom House my colleague is here now to talk about that report what are the main takeaways from the report basically this years report said that for the 4th year in the row freedom on the internet is on the decline worldwide basically the report pointed to 2 sources which you just kind of mentioned right there based on the one side we have online extremists basically extremist groups attempting to hijack the public does discourse and debate online an attempt to take into a new kind of and a democratic direction and on the other side you also have individual governments and also Government Agencies using the potential of social media to spy on their own citizens and how exactly are political extremists taking advantage of social media well i mean basically everyone is kind of seen it in the recent years i mean starting in 2016 theres been this onslaught of fake news of propaganda of distortions online especially when it comes to social media and basically it allows these these radical groups to kind of hijack the Public Discourse and take into completely new direction basically they distort the views in the opinions of people online in an attempt to kind of make them think that theyre the middle of the society is somewhere else and you know often we kind of point the finger and say this is an International Problem its coming from countries like russia like iran like china but what is actually interesting is the report indicated that a full 93 percent of Internet Users are targeted by these campaigns and theyre not coming from abroad theyre coming from internal actors within a country focusing on their own populate. And you know we hear all the time about when we go online no matter what we do our actions they are being recorded and talking about social media surveillance year it is big brother is it a serious threat or becoming one well it certainly is and i think most people especially here in europe are very conscious about the information thats that theyre putting out online typically they seem to think that its mostly corporations that are actually keeping track of them but the report indicated this year that actually increasingly governments and individual Government Agencies are tracking people more and more basically they gain access to a lot of technology that was developed for the war on terror and the war against drugs and theyre using that in a in a kind of an unregulated fashion targeting journalists targeting demonstrators targeting activists and well you could say well i have nothing to hide so whats the problem but really this is having a Chilling Effect when it comes to the Public Discourse which is really kind of something that the entire internet is based on you never know whats going to be done with the makes it even if you dont have any things actually hi aaron as always thank you thank you. And the oil spill off the northeast coast of brazil could be one of the countrys biggest environmental disasters or oil has been washing up for months now with nearly 300. 00 beaches hit but president jiah bills are not 0 has warned the worst is yet to come. Its one of the worst oil spills in brazils history but one thats hard to fully assess from the air or by satellite brazilian Authorities Say its impossible to tell how much oil is likely to come ashore and no ones sure whos responsible brazilian president says its the fault of the greeks like oil tanker and hes asked interpol to investigate but also removed environmental safeguards so they say stablish. Executive order in april got read. Several 100 of those committees in all federal. And one of those committees was exceptionally the committee to deal with oil spills now brazils coastal ecosystems its beaches coral a marine life have been devastated. By sea life wont be able to flourish and grow like its always been able to and it affects the food chain its a community of land and sea species here this is a disaster this cannot be allowed to remain. The cleanup effort is enormous including government authorities the military and thousands of volunteers because it has to be over 300. 00 beaches along 2000 kilometers of coastline must be cleared of crude oil but with this disaster with this kind of oil it cant be detected by satellite has never happened before in brazil or in fact anywhere in the world or. Brazil now has multiple environmental disasters playing out at once fires in the amazon a burst toxic mining dam. And now this. And for more im joined now by dion john tave shes a reporter for the Associated Press she joins us tonight from Rio De Janeiro don its good to have you on the program do we know more about where this oil is coming from and do we know why why is interpol now getting involved well thanks for having me so brazilian authorities investigated for 2 months they look into dozens of ships that had been netted getting close to brazil and coast around july and august and they did some testing from some poles to the beach and found that it all was coming from an agenda but they still didnt know what had happened and only a few days ago the Brazilian Police said they suspected that a greek cargo ex field the ole on its way to singapore and but the ship owner as the night that he and so brazilian authorities requested quick ration from interpol to help we believe its a geisha into the ship and the crew and the company all right so this could be a criminal investigation as well as an investigation into an environmental disaster talk to me about the impact that this is having on the environment. So i think the impact is on the environment abuse he and but its also a fisherman who depends on on. People Restaurants Hotels tourists. And people have been not doing this because they fear that the fish is contaminated and there has been some initial studies made by doing several universities here that have shown that most people would and fish was indeed contaminated and they have found while in there they just and risk respiratory systems and so the fishermen a great through a very difficult time right now and were talking about dozens of thousands of fishermen because you know its about 2000 kilometers a line and the government has said theyre going to help but might be insufficient to get rid of fishermen are not properly registered and so its creating like real problem and and as you mentioned theres also the environment i think the coral reefs could be impacted and they have already started seeing small amounts but they might be more to come and so this is terrible for the fisherman and it is in the Southern Hemisphere summer is coming what does it mean for tourism we know that brazils beaches they live from tourism. Absolutely the northeast of brazil where this is happening is a peek at this nation for christmas and new years eve which as you said flows in brazils summertime. This i see them hasnt started yet so there hasnt been that and every significance cancellations and holidays are bookings but the next couple of weeks are going to be. You know very telling well see whats going to happen but its obviously a big threat and people are scared although as for you know today there are there hasnt been a Significant Impact yet on tourism but well see what happens over christmas and you know and what about this environmental disaster for the president mr also nado he has come under fire for how hes handled this situation i mean how damaged is he said the problem that many people have said that the governments response was too slow that it was too excell too late experts and by mentalists and even people from within the government have been criticizing the governments response now we must remember that this is a very. Specific kind of all its heavy Oil Crude Oil and its moving below the surface of the water so its very difficult to track satellites film work planes monitoring dont work either so its been very difficult 1st to know what their action it was going to do and also to know if. Its that that is the old the worst of the all is behind us and has it. Young john c.
